Laser induced fluorescence of calcium dimer in supersonic jet: The red spectrum of Ca2.
01 January 1984
In the present manuscript, we obtain spectra of gaseous Ca2 cooled to 20K which are quite simple and easy to analyze. The Ca2 is produced by vaporizing the metal using a Q-switched YAG laser and entraining the dense vapor into a pulsed flow of helium gas. The gaseous species are cooled by adiabatic expansion and probed by time resolved, laser induced fluorescence.
